Borosilicate 3.3 Glass Boilers & Reboilers
Goel Glass manufactures high-performance Borosilicate Glass 3.3 Boilers designed for rapid liquid vaporization, continuous solvent reboiling, and bottom-stage heat input in glass distillation and reaction columns. Engineered by fusing heavy-duty parallel helical glass coils within an expanded glass shell body, Goel Glass boilers provide an enlarged annular vapor-liquid disengagement cross-section to prevent entrainment while optimizing heat transfer from circulating steam or hot thermal fluids.
With an average heat transfer coefficient of approximately 350 Kcal/m² · hr · °C at 3.5 bar steam pressure, these boilers deliver dependable thermodynamic efficiency with complete visual clarity and total chemical resistance against aggressive acids and solvents.

Operational Notes on Glass Boilers :
- Vapours should be passed through shell only.
- Steam should be passed in the coils at a maximum pressure of 3.5 bar which is equalant to a temperature of 147 °C.
- For higher temperature (maximum upto 200 °C) heat transfer fluids can be passed in the coils. – Cold liquids
- Cold liquids should be preheated for better results.
- Boilers should bemounted in an external circulatory loop (as shown in figure) and not direct at the bottom of flask or column
- Under certain circumstances, boilers can be mounted in series to provide larger heat transfer area.
